Introduction

Dive into the captivating world of ‘Flash Crash’, a true account of the most mysterious market crash in history that took place on May 6, 2010. In just minutes, the financial markets plummeted drastically, only to recover miraculously seconds later. The investigation that ensued led to a quiet suburban neighborhood in London where Navinder Singh Sarao, a gifted but little-known trader, was believed to be the culprit behind the crash. Journey through the events that led to the discovery of Nav’s unusual trading activities, the impact of technology on the financial market, and the ethical debate surrounding his actions.

The Mysterious Flash Crash

In 2010, the global economy was floundering from the 2008 financial crisis. Against this backdrop emerged the Flash Crash, an event that caused a lightning-fast drop in the global financial market. On May 6th at 1:41 p.m. Central Standard Time, the S&P 500 index dropped 5 percent in four minutes and the Dow Jones index fell more than ever before. Markets across the world went into panic mode, with some shares collapsing and others skyrocketing. Surprisingly, a few seconds of halted trading led the markets to recover, but the damage was done as investors, like an unemployed father who lost his small inheritance, suffered the consequences. The cause of the Flash Crash remained a mystery, leaving experts baffled.

Unraveling the Mystery Trader

At the center of a mysterious investigation in the world of trading was Navinder Singh Sarao, a gifted yet relatively unknown figure. Born to working-class parents who had immigrated from Punjab, India, Nav demonstrated an extraordinary aptitude for mathematics at a young age. His fascination with trading began in college, where he studied computer science and math at Brunel University in the UK. Intrigued by a housemate’s success in trading, Nav set out to establish himself in the field.

His journey took him to Independent Derivatives Traders (IDT), a company that trained aspiring traders. In his job interview, Nav caught the attention of IDT’s founders, the Rossi brothers, with his exceptional mental arithmetic skills. Although somewhat socially awkward, he was hired and he went on to distinguish himself as a significant asset to IDT with his incredible ability to trade futures contracts, primarily focusing on the S&P 500 E-mini.

Navinder Singh Sarao was able to sustain his remarkable success by isolating himself from the overwhelming machismo environment of the trading floor. Unassuming, he was equipped with simple ear defenders and a solitary desk, remaining focused on his work while blocking out distractions. In this way, Nav managed to transform his inborn expertise into substantial wealth.

And so, this unpretentious 35-year-old living with his parents in Hounslow, a peaceful suburb of London, rose to become the elusive figure at the center of the investigation. The astounding combination of Nav’s innate mathematical talents, determination to excel at trading, and ability to concentrate effectively would carry him to unexpected heights in the financial world.

Outsmarted by High-Frequency Trading

Nav, a skilled and peculiar trader, made impressive profits in the futures market. However, the rise of high-frequency trading leveraging advanced technologies started to outpace his abilities. Futures contracts allow businesses to hedge against risks by agreeing to buy or sell something at a predetermined price at a specific date. These contracts have attracted not only businesses but also speculators who have no interest in the actual commodity. They merely place bets on price fluctuations, turning it into a lucrative game. Nav was adept in this game, but the emerging high-frequency trading methods using cutting-edge technology and fast algorithms made it increasingly difficult for him to keep up, eventually outpacing his remarkable ability.

Outsmarting the Rigged System

Nav, a talented trader, faces challenges with the rise of high-frequency trading technology used by powerful investors, which leads to the development of his own system, Autotrader. This innovative program allows him to beat the skewed market and make tremendous profits, overcoming the limitations of his working-class background and leveling the playing field against the big hedge funds.

In a time where high-frequency trading was becoming more prevalent, Nav struggled to keep up with the rapid pace that new technology had enabled. These state-of-the-art computer programs gave a significant advantage to those who could afford them, such as big hedge funds, making the market feel rigged against Nav and others like him.

As a talented, working-class trader, Nav felt cheated and targeted by these powerful entities. Thus, he decided to take matters into his own hands, devising a way to outsmart the advanced algorithms. Nav collaborated with a computer programmer to create a system that could manipulate the data that these algorithms were reading. This strategy, known as “spoofing,” involved placing large orders to influence asset prices, only to withdraw them later.

Although spoofing was an age-old trading tactic, Nav’s newly developed system, called Autotrader, took it a step further. By executing these deceptive orders at incredible speeds, Autotrader was able to impact futures contract prices, driving them up or down before automatically withdrawing the orders. This allowed Nav to swoop in and make profitable purchases before the market could react.

Nav’s Autotrader enabled him to outwit the algorithms he once struggled against. His innovative system, rooted in his determination to level the playing field, brought him immense financial success, surpassing even professional athletes’ earnings. In doing so, Nav overcame the barriers set by his background and the seemingly rigged market, proving that talent and perseverance can triumph in the face of adversity.
